I play a lot of matches on the Cratos map with two castles... and due to that, I've fallen in love with the Chimera cards in my deck. On that particular level, since you get the +10 ST bonus at both castles, it takes no time at all to get to the max 80 ST for all Chimeras you can get on the board. Since they have first attack, as well, you're basically unstoppable... especially once you get them levelled up to avoid problems with offensive first attackers.
Plus, it's fun to watch 'em grow every time you hit that castle... they're good little monsters.
You took the words right out of my mouth pal!! Those Chimera cards are amongst my best; I had as many as 3 in my deck. I had to change it when I went to the tournament though, because I had to substitute for spells. Still great cards!!
